ELMER E. HANNA, OF CHICAGO, ILLINOIS, ASSIGNOR TO ALLIS-CHALMERS COMPANY, OF CHICAGO, ILLINOIS, A CORPORATION OF ILLINOIS.

CARRYING-'ROLLl SPECIFICATION forming part of Letters Patent No. 712,061, dated October 28, 1902.

Application filed February 6, 1902. Serial No. 92 ,814. (No model.)

To all whom t may concern,.-

Be it known that I, ELMEE E. HANNA,-a citizen of the United States, residing at Chicago, Cook county, Illinois, haveV invented certain new and useful Improvements in Carrying-Rolls, of which the following is a speciication.

This invention relates to V,rolls which areused particularly in connection with beltcarriers for belts for. elevators, conveyers,A

binations, and details of construction here inafter describedand claimed.

In the accompanying drawings, Figure l is a broken elevation of a roll constructed in accordance with these improvements; Fig. 2, an enlarged end view of one of the end pieces looking at it from the outside; Fig. 3, a side View of the mechanism shown in Fig. 2; Fig. Il, a sectional detail taken on line 4 of Fig. 2, and Fig. 5 a sectional detail taken on line 5 of Fig. 2.

In the art to which this invention relates it has long been desirable to provide a simple, economical, and efficient carrying-roll for elevator conveyor-belts, one that will have all the strength and eftciency of integral structures and yet be more economical to manufacture and repair. invention is particularly designed.

In constructing a roll in accordance with these improvements a body portion ct is provided, tubular in cross-section and preferably formed of Wrought metal, such as Wroughtiron tubing. The body portion, as above stated, is formed of a cylinder or tube, and in order to sustain it in position and provide To this end this- Ait with journals flanged end portions b are provided having journals c extending out therefrom. These Iianged end portions are preferably formed of cast-steel or malleable 5 5 iron turned down at d to fit the inner diameter of the body portion andare also provided with a plurality of lugs e, which form abutting shoulders against which the ends of the body portion rest, as at f, so asto properly 6o position the parts. These lugs also provide aplurality of spaces g, where the free portion of the ends of the body portion may be battered or hammered down, so as to lock the parts firmly and rigidly together. The body portion being made of wrought-iron pipe needs n o operation performed thereon other than the simple squaring of the ends thereof, and the only work to be done on the ianged end pieces isto turn them off at d to snugly lit the interior of the body and at c to form the journals, dispensing with all securing bolts, rivets, and keys, all of which will be readily l understood and appreciated by those skilled in the art.

I claim 1. In a roll, the combination of a tubular vbody portion, and independent anged end portions rigidly secured thereto, each having an integral journal portion extending outward axially of the tubular body portion, substantially as described.

2. In a roll, the combination of a tubular body portion formed of wrought metal, and independent flanged end portions formed of cast metal rigidly secured thereto, and each having a journal portion in xed relation thereto extending outward axially of the tubularbodyportion,substantially as described.

3. In a roll, the combination of a tubular body portion formed of Wrought metal, and independent flanged end portions formed of cast metal turned down to fit the inner diameter of the body to which it is secured, and having integral journal portions extending outward axially ofthe tubular body portion, substantially as described.

4L., In a roll, the combination of a tubular Wrought-metal body portion, independent cast-metal langed end and journal portions, and a plurality of lugs on each end portion to position the body portion and between IOO which the body portion is hammered or bent down to secure the parts together, substan- I tially as described.

5. In a roll, the combination of a. Wrought- 5 metal tubular body portion, east malleablel metal independent flanged end and journal portions turned OEE to t the interior of the body portion, and a plu rnlity of abutting lugs on each of such end portions against which the ends of the body rest and between which :o it is bent down to secure the parts rigidly together, substantially as described.
